Data error analysis program under VC++ and Win 2000 has functions of calculating equalizing value of tested data, drawing chart of residual error, system error analysis and rough error analysis. The program is compatible with testing software, data is saved and arrayis defined with chain table in CERROR Doc. Big and small of residual error and rule of sign change was observed with inspection method of residual error, and if it had system error or rough error and so on was identified. Check method of residual error was used to judge data error, as if sum of front K residual error was unlikeness with sum of back n-K residual error in measure row, it shown that exist linear system error in measure row.
